In order to avoid swaps in st02 can we set buffer size to a much higher value?

Hi there,

In order to avoid swaps in st02 can we set buffer size to a much higher value?


If we set a high value will there be any performance issues due to any other factors?



Kindly answer to my question.


Thanks & regards,

Bhushan

    Hi Bhushan,

    Yes you can increase the size of the CUA, Screen and

    Export/Import buffers until there are no swaps. For the program

    buffer, up to 10,000 swaps a day doesn't lead to performance issues by the experience.

    Hi Bhushan,

    In order to set the parameter values, first you need to check the daily swaps in history and compare it with buffer parameter values.

    Just increasing the buffers would also degrade the performance especialy initialy after system restart and until the data is loaded to the system buffers.

    Attaching ST02 screen would be helpful in providing more ides.
